We look at the division of 70757768 by 870 
We're looking to find how many times 870 goes into 70757768.

Let's proceed to step 1:
When dividing 7 by 870, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 870

Let's proceed to step 2:
870 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 70 leaves us with 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 870

On to step 3:
When dividing 707 by 870, we get 0 with a remainder of 707.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 707 leaves us with 707.
Take the next digit (5) from the dividend and append it to 707, then repeat: 7075 / 870

Let's proceed to step 4:
870 goes into 7075 8 times with a remainder of 115.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 6960 from 7075 and we're left with 115.
Append the next digit (7) from the dividend to 115 and continue with: 1157 / 870

On to step 5:
870 goes into 1157 1 times with a remainder of 287.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 287 after subtracting 870 from 1157.
Include the next digit (7) from the dividend after 287, then repeat: 2877 / 870

Going ahead to step 6:
The number 870 fits into 2877 3 times, leaving a remainder of 267.
Use 3 as the next digit of our solution. 
Result so far: 813.0
Subtracting 2610 from 2877 leaves us with 267.
Fetch the next digit (6) from the dividend, attach it to 267 and continue: 2676 / 870

Advancing to step 7:
When dividing 2676 by 870, we get 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 8133.0
Subtract 2610 from 2676 to get 66.
Bring next digit (8) of the dividend behind the 66 and repeat the process: 668 / 870

Step 8:
870 can be fit into 668 0 times, resulting in a remainder of 668.
The number 0 becomes the next digit in our result. 
Result so far: 81330.0
Subtract 0 from 668 to get 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Going ahead to step 9:
870 can be fit into 6680 7 times, resulting in a remainder of 590.
Write down 7 as next digit of the result. 
Result so far: 81330.7
The remainder is 590 after subtracting 6090 from 6680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 10:
870 can be fit into 5900 6 times, resulting in a remainder of 680.
Write down 6 as next digit of the result. 
Result so far: 81330.76
If we subtract 5220 from 5900, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Going ahead to step 11:
The number 870 fits into 6800 7 times, leaving a remainder of 710.
Put 7 as the next digit of the answer. 
Result so far: 81330.767
If we subtract 6090 from 6800, we get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Let's proceed to step 12:
870 can be fit into 7100 8 times, resulting in a remainder of 140.
Use 8 as the next digit of our solution. 
Result so far: 81330.7678
Subtracting 6960 from 7100 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
The number 870 fits into 1400 1 times, leaving a remainder of 530.
Record the quotient 1 as the next digit in the result. 
Result so far: 81330.76781
If we take 870 away from 1400, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 14:
5300 divided by 870 is 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 81330.767816
Subtracting 5220 from 5300 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
870 can be fit into 800 0 times, resulting in a remainder of 800.
Put 0 as the next digit of the answer. 
Result so far: 81330.767816
Deduct 0 from 800 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 16:
870 goes into 8000 9 times with a remainder of 170.
Record the quotient 9 as the next digit in the result. 
Result so far: 81330.76781609
Deduct 7830 from 8000 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 81330.76781609, with a leftover of 1.7e-07.
